Notes

  • S727 - 479 estimated 150,000. 37 adjusted to 155,000. 261 counted 94,000 staging in W Alaska in Sep 1997.
  • S6592 - Substantial rate and period of decline, well documented across flyway but no new estimate published. WPE5 estimate is much lower than for WPE4 (some experts suggest an even lower estimate) and is derived from preliminary analysis pending outcome of ongoing comprehensive analysis by University of Queensland.
